Abstract

In this model analysis device, a model acquisition means acquires a model. A dataset acquisition means acquires a dataset. A performance calculation means calculates the performance of the model for each attribute corresponding to each category in the dataset. An output means outputs performance information indicating the calculated performance of the model for each attribute.
